I have a weird problem. I'm using MATLAB 2010a with RTWT. It works fine with my own notebook computer. But I will use it in another PC. This PC is a mobile one and it takes its power from Lead Acid batteries through M4-ATX 250W DC-DC Power Supply. The board has Intel i7 3.2Ghz processor and 4GB DDR3 Ram with Windows 7 installed on a Solid State disk.
The problem arises in this computer. When I start the rtwt simulation in this computer, independent of the model complexity, it runs too slowly. My sample time is 0.001s (I tried 0.01 and 0.1 too with no luck). When I start the simulation, it takes nearly 4-5 seconds or more to achieve 1second in simulation. So rtwt is not running real time.
I tried reinstalling both MATLAB and rtwt kernel but it did not help.
The only thing that comes to my mind is the power supply. If its wattage (250W) is insufficent for this processor with rtwt simulation running, does it cause such a problem? If it is not, any suggestions will be welcomed.
Thanks a lot..
